The present invention drives hydraulic station work by variable-frequency motor, and then drive the 3rd hydraulic cylinder piston respectively by hydraulic oil pipe, the action of the 4th hydraulic cylinder piston, connect or seal first intake pipe chronologically, second intake pipe, first outlet pipe, second outlet pipe, simultaneously, drive first hydraulic cylinder piston chronologically respectively, the action of second hydraulic cylinder piston, will with first hydraulic cylinder piston, water pump in the room of the second hydraulic cylinder piston UNICOM is delivered to pump housing water outlet, realize the purpose of remote fluid power control pumping, concrete working procedure is: at first, the 3rd hydraulic cylinder piston drives the action of first slide block, make second through hole and the described first intake pipe UNICOM that are located on first slide block, and second intake pipe is sealed; The 4th hydraulic cylinder piston drives the action of second slide block, makes the third through-hole and the described second outlet pipe UNICOM that are located on second slide block, and first outlet pipe is sealed; Simultaneously, first hydraulic cylinder piston is with path inspiration first room of the second through hole formation of the water outside the pump housing on water intake, first intake pipe and first slide block; Second hydraulic cylinder piston then is pumped to the water outlet that is provided with on the pump housing with the water in second room by the path that the third through-hole on second outlet pipe and second slide block constitutes; Then, hydraulic station switches the fuel feeding direction, makes the 3rd hydraulic cylinder piston drive the action of first slide block, makes second through hole and the described second intake pipe UNICOM that are located on first slide block, and first intake pipe is sealed; The 4th hydraulic cylinder piston drives the action of second slide block, makes the third through-hole and the described first outlet pipe UNICOM that are located on second slide block, and second outlet pipe is sealed; Simultaneously, second hydraulic cylinder piston is with path inspiration second room of the third through-hole formation of the water outside the pump housing on water intake, second intake pipe and second slide block; First hydraulic cylinder piston then is pumped to the water outlet that is provided with on the pump housing with the water in first room by the path that second through hole on first outlet pipe and first slide block constitutes, and moves in circles, and can realize the purpose of pumping.
The working principle of the another kind of structure of the present invention is: utilize first oil hydraulic motor, second fluid motor-driven, first cylindrical slider, second cylindrical slider to rotate, switch the break-make of first intake pipe, second intake pipe, first outlet pipe, second outlet pipe in real time, the purpose of same pumping.
Advantage of the present invention is sketched in following:
1, the present invention relies on hydraulic station that transfer motion power is provided, and drives the hydraulic cylinder piston that is arranged on the pump housing by hydraulic oil pipe, realizes the purpose of pumping fluid; Realize dynamo-electric separation, telecontrol.Changed that the traditional water pump motor closely links to each other with impeller, primary power supply and the inseparable mode of structure of pump head, solved traditional water pump and under sudden a large amount of infiltrations of mine and high concentration gas environment, used many-sided accident potential that may bring.Particularly overcome traditional water pump, in case pumping plant is flooded, water pump just can't be worked, and plumbing is speedily carried out rescue work and caused the defective of sizable difficulty.Hydraulic Double altitude fluid pump of the present invention can be positioned over hydraulic station outside the well, pump head is positioned over the bosom, down-hole, middle with the oil pipe connection, ground hydraulic station provides power by hydraulic oil pipe to the pump housing, does not also influence its proper functioning in the entry even the pump housing all floods at all.And, because power supply only need be supplied with pumping plant, do not enter mine, can effectively reduce the probability that down-hole accident takes place.
2, the present invention adopts variable-frequency motor to drive, and when motor can not move under full load, except that reaching the motivational drive requirement, the consumption that unnecessary moment has increased active power caused waste of electric energy.Frequency control motor can meet the demands by the rotating speed that reduces main oil pump motor, has improved the utilization rate of equipment.When motor moves under full load, because the effect of the inner filter capacitor of frequency variator, thereby reduced reactive loss, increased the active power of electrical network.Utilization frequency conversion soft start function, inrush current is little, and maintenance workload is little, has alleviated inrush current on the one hand to the impact of electrical network with to the requirement of power supply capacity, on the other hand, energy saving.Overcome conventional pump and realized Flow-rate adjustment, defective that can not be energy-conservation by valve throttle.
3, the present invention utilizes frequency control motor to control the operating frequency of oil cylinder and plunger in real time, realizes control pump discharge in real time.
4, the present invention adopts hydraulic station as power, drives the hydraulic jack to-and-fro motion, and continuous action reaches the purpose that sucks fluid and discharge fluid.This structural type has two big significantly characteristics: the one, and the efficient height, because after fluid enters room, be to discharge from the outlet port under the situation of no any leakage, so can not occur curved efficient collection of illustrative plates with the variation of lift, its efficient can reach more than 98%.And common lift of pump efficient is generally 50-86%.The 2nd, the lift height, the pressure of hydraulic station transmission is generally at 25Mpa---between the 30Mpa, effect exchange by oil cylinder and piston cavity area, the size of exerting oneself of piston is directly proportional with the pressure of oil cylinder in the piston cavity, be directly proportional with the area of cylinder barrel plunger, therefore the fluid pump lift can be from tens meters to 3000 meters, even higher.Compare with multistage pump and hydraulic double-altitude fluid pump: power is all 90kw, the draining bore is all 0.25m, and the multistage pump flow is 108m 3/ h, lift are 180m; And the two high pump dutys of fluid power can reach 125m 3/ h, lift can reach 950m.
The present invention has overcome traditional high-lift pump such as plunger pump, Multiple Sinking Pump, deep-well pump, the inherent disadvantage of wing pump, as: though plunger pump lift height flow is little, generally at 30m 3About/H, general employing piston rod mode work done on the structure, working life is not long, and is fragile; The flow of Multiple Sinking Pump and deep water pump and lift belong to medium level in water pump industry, but limited by the place when using, and generally should be used for mechanical well and hand excavation's well; Though the wing pump flow is big, lift is not high, particularly its working efficiency increasing and progressively weaken with lift.
In sum, the present invention simple and reasonable, easy to operate, realize that by fluid power control the pump housing separates with electrical source of power, Flow-rate adjustment is convenient, lift is high, efficient is high.Be suitable for fields such as recharge in the oil field, mine drainage, be specially adapted to sudden mine water drainage.
